The braking performance of carbon fiber road bike wheel can be a topic of consideration, and it does have some distinctive characteristics, especially when compared to aluminum wheels. Here are some points to keep in mind:

Heat Dissipation: One challenge with carbon fiber rims is that they are not as effective at dissipating heat as aluminum. During prolonged or heavy braking, carbon fiber rims can heat up more, potentially affecting braking performance.

Wet Conditions: Traditionally, carbon fiber wheels were criticized for reduced braking performance in wet conditions compared to aluminum rims. Water on the brake track could diminish friction, resulting in longer stopping distances and decreased overall braking efficiency.

Advancements in Brake Track Technology: Many modern carbon fiber wheelsets have addressed the issue of poor wet-weather braking by incorporating advanced brake track technologies. Textured or treated brake tracks, as well as specific brake pad compounds designed for carbon rims, can significantly improve braking performance, even in wet conditions.

Disc Brakes: Some road bikes are now equipped with disc brakes, which provide more consistent and reliable braking in various conditions, including wet weather. Carbon fiber wheels designed for disc brakes may offer improved braking performance compared to their rim brake counterparts.

Brake Pad Selection: The choice of brake pads plays a crucial role in the braking performance of carbon fiber wheels. Using the recommended brake pads for your specific carbon rims can make a significant difference.

Rider Technique: In wet conditions, riders may need to adjust their braking technique to accommodate potential differences in stopping power. This might include applying the brakes earlier and more gradually to allow for the reduced friction on wet brake tracks.
